Pressure Sensor

A circular ceramic pressure sensor has a 1 cm diameter diaphragm with thickness of 200 microns. The Elastic Modulus for ceramic is 8 x 1010 N/m2. Assume poisson's ratio is 0.2. The capacitive gap is filled with air. a) How much does the center of the diaphragm deflect for a pressure of 100 kPa? b If the initial capacitance of the sensor is 100 pF, how much does it change for a pressure of 1 kPa
